ValiMail CEO Alexander García-Tobar explores this question today in InformationWeek’s Dark Reading. The article explains how email’s historic lack of authentication came about, why that’s a problem today, and how DMARC can help solve that problem.
The good news is the situation is beginning to change for the better, thanks to a movement toward email authentication led by the major email service providers, including Google, Yahoo, AOL and Microsoft. These entities have recently converged around a set of open email authentication standards called DMARC (Domain-based Message Authentication, Reporting, and Conformance). It’s the keystone global standard, integrating two older authentication standards and aligning them in a way that makes it possible to authenticate the identity of an email sender easily, reliably and quickly — essentially creating a white list of acceptable senders of email, and blocking unauthorized senders from delivery.
